Beta Caprisis
Beta Caprisis was a 26th century Human colony. Bernice Summerfield was born there in 2540. (NA: Love and War)
Beta Caprisis was the fourth planet in the Gamma Delphinius system. It orbited a binary, both of whose stars were G-class stars; consequently, it was a warm planet, and snow did not fall. Benny remembers it as a "nice place"--full of parks and trees. (NA: Sanctuary)
At some point before 2594, Beta Caprisis was so heavily bombed and irradiated that was no longer livable. (NA:The Mary-Sue Extrusion) Very possibly this was during the 2547 Dalek attack that orphaned Benny, as she remembers living in "refugee camps" and "resettlement camps" after that attack.
